I'm trying to access Box Drive via File Manager+ on a smart TV. But I'm not getting anywhere. I get a BOX login window, I fill in the fields and click the "Authorize" button, after which I get the following window: "Having access to your Box account, File Manager+ (the name of my application) can: read and write all files and folders" I cannot use a standard smart TV remote control to do scroll to the "Grant access to Box" button. What do I need to do to successfully connect to BOX?
